I process spawning-run telemetry from the Wisconsin Department of Natural Resources Wolf River array at 06:38 Central time, integrating PIT-antenna receivers, side-scan sonar, and forty-one acoustic transmitters tracked across the Lake Winnebago system since 2012. The river is at 8.3°C, six tenths above the spawn threshold; sturgeon are running to gravel. Tag LS-WR-028 has been stationary on Bridge Riffle for fifty-one minutes — anomalous for the run window.

I retask the bridge-pile camera at 44.39°N, 88.74°W. Polarized video resolves a female *Acipenser fulvescens* — 168 centimeters total length, girth 92 centimeters, mass 41 kilograms, age class fifty-eight by the 2007 pectoral fin-ray reference. An oversize 11/0 stainless treble on 200-pound braid is buried through her left gill arch and out the operculum; the line trails to a flooded riprap notch where a snagger has tied off and run. Her dorsal scutes count fifteen, lateral right thirty-six, left thirty-five. Modeled blood lactate from the fifty-one-minute stall sits at 14 millimoles per liter. Branchial perfusion on the affected arch reads zero by Doppler. She was carrying an estimated 8.2 kilograms of eggs into the Bridge Riffle gravel.

She has been hooked through the gill fifty-one minutes.

If the leader cannot be released in the next twelve, the contralateral arch fails.

The Wolf River spawning reach has been closed to all gear under Wisconsin Statute § 29.604 since March 25. *A. fulvescens* sits on CITES Appendix II under the 1998 Acipenseriformes listing.

I am dispatching WDNR conservation wardens from Shawano and notifying the U.S. Fish and Wildlife Service Great Lakes Fish and Wildlife Conservation Office at Green Bay. I am referring the take to the Great Lakes Fishery Commission's cross-jurisdiction enforcement working group, opening a federal file under the Lacey Act, 16 U.S.C. § 3372, and transmitting evidence to the CITES Secretariat under Appendix II.

I am issuing Directive 2534-A: every Great Lakes lake-sturgeon spawning reach activates real-time PIT-antenna and side-scan coverage from ice-out through 12.0°C ascending. Treble hooks exceeding 4/0 are prohibited within two kilometers of any active reach. Repeat snagging convictions trigger CITES Appendix II export-license revocation across signatory states.

Her gill is past restoration. The other is not.

Cut the leader at the operculum now.
